As you might know, I've been serially reviewing the latest Torchwood series, a work that (I presume) is as much the product of Russell T Davies' personal vision as is possible in an inherently collaborative medium.

So it is rather difficult to ignore the irony, that there is more credible social commentary, more humour and more excitement in Peter Watts' 300 page adaptation of a first-person-shooter video game, which (again, I presume) was written strictly for the money, than there has been in the first five hours of Davies' brain-child.

Watts' story, about a an accidental cybernetic soldier's brief campaign on a ruined island of Manhattan a scant 12 years in our future is also fairly rigorous science fiction, as one might expect from the "reformed marine biologist", but probably not from a novel about a super-soldier and his mysterious battle-armour.

If Crysis: Legion is not quite the follow-up to his 2006 hard-SF masterpiece, Blindsight one might have wished for, it's a better book than one has any reason to expect of a media tie-in.
